VREVERSIBLE: FULCRUM AND METHOD or MAKING Application led March 20,1920. Serial No. 367,369.

To all whomc't may concern.

Be it known thatI, ARMAND H. PEYCKE, a citizen of the United States,residing at Chicago, in the county of- Cook and State of Illinois, haveinvented certain new and useful Improvements in vReversible Fulcrums andMethods of Making Same, of

which the following is a specification.

This invention relates to an improvement in reversible fulcrums andmethod of making same.

The objects of this invention are to provide a simple and improvedreversible fulcrum and a simple and improved method of making the same.y

These and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheet of drawings, in Which- Figure 1 is aplan view of a reversible fulcrum embodying my invention and disclosingthe method by which same is formed;

Figure 2 is a side elevation of the same fulcrum; and

Figure 3 is a sectional view taken in the plane of line 3 3 of Figure 2.

The various novel features of the invention will be apparent from thefollowing description and drawings, and will be particularly pointed outin the following claims.

Referring to the figures of the drawings, it will be noted that I have.provided a fulcrum consisting primarily of three main parts, 10, 11 and12, the part 10 being the lever supporting member, the part 11 being anintermediate support embracing the lever supporting member 10, and thepart 12 being the strut which embraces the intermediate support 11. Theintermediate support 11 preferably, and as shown, is in the form of anendless band.

The lever receiving member 10 is first formed, either by casting orforging, and has a slot 13 for receiving the lever, and also hastrunnion portions 14 and 15, whereby the fulcrum is reversible. Theintermediate support 11 is next formed around the lever supportingmember 10. This intermediate support 11 may be forged around the member10 or cast around the same. In the latter case, the lever supportingmember 10 will Vact as a core, as described in my copending application,Serial No. 367,367, filed March 20, 1920, the surfaces of said leversupport- Specification of Letters Patent. Patented Feb, 7, `1,922,

in various adjusted positions,

. ing member being provided with some suit-v able Parting medium, Suchas Shellac, t0 prevent the adherence of moltenfmetal.

In forming the'intermediate support 11,v the same isprovided withtrunnion receiv-` ing portions 16 and 17 to rotatably receivethetrunnions 14 and 15 'respectively off the lever supporting mem-ber 10.Also, the'intermediate support has its sides or legs provided withconcave portions 18 to loosely receive the lever supporting member, asshown particularly in Figure 3. This intermediate support 11 also isprovided with anges 19, between which are received the sides or legs ofthe strut 12, the strut preferably being of forged metal and bent aroundthe intermediate support, after having been provided with a tension rodseat 20, and having the rear ends 21 and the legsl bent laterally forattachment to the compression member of the brake beam. p

To secure the lever supporting member 10 have rovided the trunnionportion 15 with t ree slots, 22, 23 and 24, which may receive a key 25for locking purposes. By providing three slots in the trunnion portion15 of the lever supporting member, the lever receiving slot 13 may takea lever atthe usual forty degrees to either side of a vertical position,or take the lever in a vertical position to meet all operatingconditions.

It is my intention to cover all modifications of the invention fallingwithin ther spirit and scope of the following claims.

I claim:

1. A reversible fulcrum, comprising a 4. A lreversible fulcrum,Comprising a lever supporting member, an intermediate support 1n whichsaid member is rotatably mounted, said intermediate support havingflanges, and a strut formed around said intermediate support and beinglooatedinten mediate said flanges.

lever supporting member in a plurality of positions Within saidintermediate member.

7. The method of making a reversible fulcrum, consisting rst in forminga lever sup ortingmember, then forming an interme iate support aroundsaid member, andthenV forming a strut around'said intermediate support.v Y 8. The method of making a reversible fulcrum,loonsisti ng first informing a lever supporting member with trunnions', then forming anintermediate support around said member with trunnion receivingportions, and then forming a strut around said intermediate Support.
